What can you conclude from the graph?
a) do you reaction that causes a firework to explore requires less energy just start and occurs more rapidly than the reaction that causes the candle to burn
b) the reaction that causes a firework to explore requires less energy to start and a curse less rapidly than the reaction that causes a candle to burn
c) the reaction that causes a firework to explore requires more energy to start an occurrence less rapidly than the reaction that causes a candle to burn
d) the reaction that causes a firework to explode requires more energy to start in occurs more rapidly than the reaction that causes a candle to burn

I believe the answer is: A) do you reaction that causes a firework to explore requires less energy just start and occurs more rapidly than the reaction that causes the candle to burn

The energy needed to start the reaction should be shown by the bump at the begining of the reaction. The bump shown by blue line(candle) is much higher than bump made by the orange line(firework). The reaction of firework also happens more rapidly which shown by the fact that the orange line is always on the left of the blue line.

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
